Titles of Primary Sidebar

How can I change the titles of the primary sidebar widget area?

And how can I change the small purple line (I have the black color theme) under the title of the sidebar widget area?

Thank you.

Hi maggiemae,

To change title please go to Appearance->Widgets and change title for each widgets as given in the screenshot.



Now, to change small purple line please paste the code given below in custom css.
(Appearance->Theme Options->Styling Options->Custom Css) of your dashboard.

Code:

.sidebar h3 {
background: none;
border-bottom: 1px solid #E8E8EB;
}

Thanks,
Praveen
